I think their characters on screen behavior have as big an impact on opinions of them personally as their real life off screen behavior. It's evident no matter which pairing an actor is with - and it affects a number of actors/characters. The fans of the couple they are currently featuring tend to be much more tolerant and readily charmed - while the fans of their opposite pairings are easily offended/frustrated. And I include myself when I say that - and not the fans who simply don't like the actor/character no matter who they are paired with.
